Abstract

Increasing concern of greenhouse gas emission had been a chief highlight in inducing global warming. Application of Ordinary Portland Cement (OPC) for oil well cementing contributes a large portion for these gases, and therefore, geopolymeric technology is proposed to help curb down CO2 emission by replacing OPC. However, enough justification has to be shown to ensure the new technology is reliable enough to replace OPC for oil well cementing. This study aims to study the effect of silica fume addition to low calcium fly ash geopolymer cement by focusing on compressive strength and other properties such as thickening time, fluid loss and acid resistance test. Low calcium fly ash pose geopolymeric properties besides having a very low utilization rate which justify fly ash as our base material. Five different composition of varying silica fume (SF) content (0, 5, 10, 15 and 20%) was prepared and cured under wellbore condition (3000 psi and 200 F) under two curing time;8 hour and 24 hours, before being tested for compressive strength. Composition with 15% SF posed highest compressive strength of 5.6MPa (8 hours time) and 11.6MPa (24 hours time). Acid resistance test was conducted by immersing the 15% SF mould in 4 different HCl and 35% reduction of strength was observed for both mould cured at different time.
